Description

Technical Field

[0001] This utility model relates to the field of plywood cutting, and in particular to a plywood cutting device. Background Technology

[0002] Plywood is a three- or multi-layered sheet material made by rotary cutting logs into veneers or slicing timber into thin sheets and then gluing them together with adhesives. It usually uses an odd number of veneer layers and glues the adjacent veneer layers with the fiber directions perpendicular to each other.

[0003] Plywood, a common building and furniture material, is widely used in interior decoration, furniture manufacturing, packaging, and other fields. Cutting is one of the key processes in plywood processing, directly affecting the dimensional accuracy and processing efficiency of the product. The sawdust and dust generated during the cutting process not only affect the working environment but may also endanger the health of workers. Existing equipment has poor dust removal performance, and dust is thrown out with the high-speed rotation of the saw blade during the cutting process, thus affecting the processing environment. Therefore, we propose a plywood cutting device to solve the above problems. Utility Model Content

[0027] The working principle of this utility model is as follows:

[0028] In use, the cutting device is first supported by the support leg 15, the power supply of the cutting device is turned on, and the controller 13 controls the adjustment mechanism 5 to drive the positioning plate 2 on the cutting table 1 to slide and adjust. The plywood is placed on the cutting table 1 so that one side of the plywood contacts the positioning plate 2. After adjusting the cutting position, the control device is started. The first motor 901 drives the cutting blade 902 to rotate through the rotating shaft 904, pushing the plywood to move along the positioning plate 2. The plywood first cooperates with the roller 19 on the sliding dust cover 10. With the cooperation of the roller 19, the sliding dust cover 10 automatically adjusts its height according to the thickness of the cutting material. During the cutting process, the vacuum cleaner 7, in conjunction with the sliding dust cover 10 and the fixed dust cover 17, collects the debris during the cutting process, thereby ensuring the cutting environment.
